Manual Iris Lenses
Set Lens iris to the required F. number when applicable.
Heavy lenses
Heavy lenses need additional support from a housing or base plate in order to withstand vibration or shocks. Use the correct spacer height to align supported lenses in order to prevent torque damage of internal camera components.
Follow these steps to mount a lens on the camera:
1)Remove the dust cap, and screw the lens into the lens mount.
2)Where applicable, connect the iris control cable for automatic iris control to the lens connector.
